Panasonic Lumix DMCZS7 12.1 MP Digital Camera with 12x Optical Image S Comments:

5.0 out of 5 stars Very Good Photos with Great Video,
March 18, 2010 This review is from: Panasonic Lumix DMCZS7 12.1 MP Digital Camera with 12x Optical Image Stabilized Zoom and 3.0Inch LCD (Blue) (Electronics) I’ve got my ZS7 today the camera is just great! A superior Leica lens with a highresolution sensor, advanced image processing, and plenty of sophisticated features in a small but very solid and stylish body.

PROS:

Solid metal body, stylish design, nice darkblue color
Very convenient onehand grip, unusual for such a small pocketsize body
Short startup time (11.5 sec), no shutter lag, fast auto focus
A dedicated Moviebutton for instant recording
Big 3″ colorful “juicy” display visible even in direct sunlight
Intuitive menu plus very convenient Quickmenu with a dedicated button
Excellent quality Leica lens: sharp and contrast in the entire zoom range
Wide 25mm (35mm equiv.) is very convenient for indoors
Huge 12x optical zoom (up to 300mm equiv.) in such a compact design
Twospeed of zooming fast/slow controlled by the lever
Smooth and silent auto focus and optical image stabilization
Best in the industry “iAuto” mode you can really trust it!
New “Intelligent Resolution” feature greatly improves the image quality
Creative Aperture and Shutterpriority and full Manual modes
Three independent scenery modes including “High Dynamic” range scene
New GPS feature for those who travel a lot
Very good movie quality in 720p AVCHD mode looks like a full 1080 HD one
Highquality stereo microphones
Accepts SD/SDHC and new SDXC huge capacity memory cards

CONS:

A mechanical lever for switching between shooting and playback modes
Some soft “shshsh” noise while zooming in and out (but no “clicks”)
I wish more sensitivity for lowlight shooting

BUILD: The ZS7 camera looks and feels as good as it’s predecessor DMCZS3. The design is almost as the same, just the power switch and the mode dial exchanged their places. One significant addition a GPS mark on the top, right above the lens. The blue color is not that dark as on TZ5 and not so striking bright as on ZR1. A slight dent on the back with some prominence on the right side makes a very convenient grip to operate with one hand. A metal body looks pretty solid, however it is not that heavy.

PERFORMANCE: The new camera has a pretty good performance: the startup time is a little bit more than 1 sec and with almost zero shutter lag. Taking into account a new very quick “Sonic Speed” auto focus, which takes about 0.350.4 sec, you will be able to catch virtually every spurofthemoment photo. And a dedicated movie button allows starting video recording at any time without any preparation.

LENS: Leica lens is just excellent: unusually big for a so small body 12x zoom starting with the very convenient for indoors shooting 25mm up to telephoto 300mm (equiv.) plus a quick and precise auto focus (however might be somewhat slower in lowlight), and good optical image stabilization in conjunction with the digital one which allows you to take sharp pictures in the entire zoom range and at the very low shutter speed around 1/8 and even 1/4. The autofocusing and optical image stabilization work in absolute silence, and the only zooming produces some soft “shshsh” noise. Good news without any start/stop clicks on the footage .

DISPLAY: A large 3inch highresolution LCD monitor with 460K pixels has a very good contrast and saturation the pictures look very “juicy”. The brightness also is high enough to be seen even in a direct sunlight (just a bit darker) and in a wide angle of view. All that allows to share photos and videos immediately with other people.

MENU: For those who used the Panasonic P&S cameras before the ZS7 menu looks very familiar, just some new items added. Also there is a QuickMenu button which is very helpful for a quick access to the most frequently used settings. The new camera has such a luxury as the Aperture, Shutter speed, and Manual modes and there is a new Exposure button (next to the video one) which allows to set manually the aperture using the LeftRight buttons and the shutter speed with UpDown buttons.

AUTO SETTINGS: The best in the industry Panasonic’s Intelligent Auto mode is getting better with each new model. Actually it’s a whole bunch of sophisticated algorithms which help to take really nice pictures with minimum efforts. They are worth to be aware about so here is a brief list of most effective of them.

“Intelligent Scene Selector” It quickly analyzes the light conditions as well as focusing results and selects either portrait, scenery, macro, night portrait or night scenery. It also displays a small icon of the chosen scene in the top left corner. The feature is extremely helpful when you need to shoot very fast on spurofthemoment.

“Intelligent ISO” If camera detects that your subject is moving, it raises ISO and shutter speed to take shots without motion blur, otherwise it will try to keep the lowest possible ISO to reduce noise and to get nice clear pictures.

“Intelligent Exposure” it’s a kind of a small brother of the High Dynamic Range feature. If the camera sets the correct overall exposure but some areas happen to be too dark, this feature automatically increases the brightness of the dark areas to make the entire picture to look more balanced. It also pretty effective for the backlight conditions instead of getting just a silhouette of your subject against the bright sky it makes the subject normally exposed but without washing out the nice blue sky.

“Face Detection” is another great thing for taking goodquality pictures of people. It happened to me a number of times in the past that a presence in the frame of a more contrast element somewhere behind the person I’m taking picture of was making the camera to adjust focus at that unimportant distant object and therefore made the major person outoffocus. The same way if there is a bright background behind the person then the camera will measure the luminance of that background while the person’s image will be pretty much underexposed (dark). The Face Detection feature identifies the human faces and tells the camera to adjust focus and exposure for the faces first so the people on the picture will be looking well exposed, clear and sharp.

ADVANCED FEATURES: I guess the most interesting and advanced is a new “Intelligent Resolution” feature. Actually it combines a sophisticated noise reduction with a new picture enhancement algorithm. This feature automatically identifies the 3 type of the picture areas: outlines, detailed textures, and smooth gradation panes and provides an optimized handling for each of them separately. As a result the photo looks sharper at the edges and more clean in between. Many old P&S cameras had pretty fast picture quality degradation at the ISO around 300400 and higher. The shots taken by ZS7 even at ISO 400 look pretty good on the small and even mediumsize prints.

IMAGE QUALITY: Imagine on a sunny day you take an outdoors picture of a wall made of the new brown bricks with a $3000 DSLR and a small P&S camera from the distance about 68 feet. How could you recognize by which camera was taken a certain shot? The subject is plain so no DepthofField is involved into comparison. However in this example the two characteristics will help to distinct the cameras: 1) The edges of bricks will be well outlined on DSLR shots and a kind of fuzzy on the P&S ones; 2) The new bricks do not have any structure on their sides, they are just plane and so exactly that way they will look on the DSLR shots, while on the P&S ones their sides will show more or less amount of noise. If you perform the same test for an evenly cut line of bushes (again DOF is not involved) you will see the same result plus the internal structure of each leaf will be more clear on the DSLR photos. So to make pictures taken with your P&S camera looking like the DSLR ones the P&S camera should make the outlines sharper, clean the noise on the plane or soft gradation areas, and slightly emphasize the internal structures, if any. That is exactly what the new “Intelligent Resolution” (IR) feature tries to do.

The “iAuto” mode in ZS7 is organized the way that you will have decent, good photos in virtually any situation right outofthebox. The several hundreds shots I took by now look good on my 24″ display and so they will on the similar size prints. But if you look at them at 100 crop (magnification) then on many of them you might find some areas which do not look natural. If the IRalgorithm decides about a certain lowcontrast part on your picture that it’s a plane area then it will remove all the noise altogether with all the subtle details from that part of the picture. If you take a picture of a big tree with hundreds of branches (but without leaves) against a bright sky the IRfeature will treat it as a structured area and will slightly sharpen it to look clearer. But when you take a landscape picture with many distant trees in front and behind, those hundreds of crossing branches will create a lowcontrast pattern which together with internal sensor’s noise might look for IRalgorithm as just a noisy plain area and so it will obliterate all the details leaving only some average color in that part of the picture and so making it looking very unnatural. The thing is that unlike the previous models the noise reduction in ZS7 is pretty strong. I would not call it “aggressive” but it’s really strong.

QUALITY IMPROVEMENTS: There is a way how to get the best out of this camera while shooting landscapes on sunny days. Here is a recipe for experienced amateurs:
Switch the mode dial to the program “P” mode.
Press the Menu button and select the lowest… Read more ›

5.0 out of 5 stars Improves on the already great ZS3!,
April 4, 2010 This review is from: Panasonic Lumix DMCZS7 12.1 MP Digital Camera with 12x Optical Image Stabilized Zoom and 3.0Inch LCD (Black) (Electronics) I just replaced my trusty ZS3 with the new ZS7 and, so far, I am very pleased with this camera. The output is much cleaner and smoother than the ZS3′s, much more refined. Compared to the ZS7, the ZS3 produced images that look brittle and overprocessed. As with virtually all smallsensor cameras, the ZS7′s images are a little noisy (even at base ISO) if you look close enough. But noise is far less objectionable than ragged edges and smeared details, which is what I usually got from the ZS3. The images I’m getting from the ZS7 look surprisingly good even at 100 onscreen enlargement; whereas the ZS3′s output was virtually unusable at this magnification. The improvement is dramatic. Considering that the ZS7′s resolution has also increased from 10 to 12 MP (it’s actually a 14 MP sensor that is masked to create different aspect ratios), I’d say that Panasonic has done a really good job here.

The ZS7 improves on the ZS3 in several ways; but for me the most important new feature is Picture Adjustments, which let you turn down the amount of sharpening and noise reduction that are automatically applied to every image. Photographers who do their own postprocessing will appreciate the ability to apply their own preferred methods of sharpening and noise reduction.

The next most important new feature (imho) is the addition of aperture/shutterpriority shooting modes. There isn’t much latitude for adjusting the fstop in most smallsensor cameras because of defraction effects; but it’s great to be able to control the shutter speed manually.

The ZS7 also adds GPS, which can (thankfully) be turned off. Leaving it on shortens battery life.

Other improvements that I appreciate include (1) improved image stabilization, (2) new Venus processing engine, (3) High Dynamic mode, and (4) the LCD now has a good antiglare coating.

All things considered, the ZS7 is an impressive upgrade that is easily worth the price.
